I mentioned the CHKNTFS command in tip 0008 » Stop CHKDSK from running at boot time.
I described the AutoChkTimeOut Value Name in tip 0787 » Autochk countdown timer.
Windows XP add the /T switch to the CHKNTFS command, which sets the AutoChkTimeOut Value Name.
When you type CHKNTFS /? in a Windows XP CMD.EXE window, you receive:
Displays or modifies the checking of disk at boot time. CHKNTFS volume \[...\] CHKNTFS /D CHKNTFS /T\[:time\] CHKNTFS /X volume \[...\] CHKNTFS /C volume \[...\] volume Specifies the drive letter (followed by a colon), mount point, or volume name. /D Restores the machine to the default behavior; all drives are checked at boot time and chkdsk is run on those that are dirty. /T:time Changes the AUTOCHK initiation countdown time to the specified amount of time in seconds. If time is not specified, displays the current setting. /X Excludes a drive from the default boot-time check. Excluded drives are not accumulated between command invocations. /C Schedules a drive to be checked at boot time; chkdsk will run if the drive is dirty. If no switches are specified, CHKNTFS will display if the specified drive is dirty or scheduled to be checked on next reboot.
